To say more would spoil the adventure, but suffice it to say that the bulk of the movie is a lilting, literary, lovely, and luminous trip, a marvelous way to explore the issues that most affect Gil, and quite unlike any "mid-life" crisis that I've seen before.
In part, of course, that's because Woody Allen is at the helm.
Having made dozens of pictures, criss-crossing often through the broad avenues of wealth, privilege, and neurosis, Allen has developed a distinct motif -- make that numerous motifs -- that reoccur often and, perhaps, without Allen even realizing it himself. He writes to his strengths, and his films live and die on the material. Midnight in Paris is his best material in years.
